I think it depends on the vet you talk to hyper. My vet supports me feeding raw, but he also is the vet for a zoological center, and it's not like they feed the tiger's kibble ya know? He says there are risks with any diet, and he feels raw is the best option for my dogs.
And yes, dogs CAN get salmonella, ecoli, and just about any other nasty. Which is why you should always handle their food as if it were for you. However, dogs do have a more acidic stomach and a shorter digestive tract than humans, which makes them less susceptible to food poisoning.
If the meat is close to turning, and not something I myself would eat, I don't feed it to my dogs. However, my dogs take bones out in the yard, let them get good and "ripe" (we've got one nasty, juicy bone that's been out there for a month or so), then attempt to drag them in the house and onto the living room rug to eat them
Apparently it tastes better "aged"
. My dogs also eat poop - theirs, my kid's (he doesn't always flush), the neighborhood cat's...you get the picture. If they can eat poo, and dead things they find, and nasty ole' rotting bones from the yard, I hardly think a raw egg or some fresh, clean raw meat is gonna hurt them.
As far as nutrition from a cooked protein versus a raw protein? It's six of one half a dozen of the other. Cooking a protein denatures (damages) some of the enzymes and amino acids (good stuff), lowering its nutritional value. On the other hand, there are just as many enzymes and amino acids which humans (and dogs I would imagine) cannot digest raw, we need them to be denatured in order to use them. The problem with a cooked diet is you can't cook the bone or it becomes dangerous. You can feed a cooked diet and supplement bone meal, but it's kind of a pain (in my opinion). Plus, raw bones are great for keeping teeth clean, keeping doggy busy and building jaw strength. I feed raw because my dogs love it, it keeps their teeth and jaw healthy, and I'm lazy
